看守世界研究中心的《世界現況》報告已成為卓越的人類智慧資產。其除了關注地球的物質現況，對於與全世界生態系統、自然資源息息相關的人類系統，也提供了洞見與了解。這本《世界現況》清楚地說明若我們不做改變會有什麼後果；而採取行動避免氣候變遷最糟的影響，又可以達到什麼樣的未來。
《2009世界現況》在處理這個挑戰時，適切地架構出因應策略，不僅強調新技術的重要性，也從人類行為與選擇的角度，指出非常不ㄧ樣的作法。

Greenhouse Gas Emissions from Land Use * The greenhouse gas impact of 1 unit of nitrous oxide is
equivalent to 298 units of carbon dioxide; 1 unit of methane is
equivalent to 25 units of carbon dioxide.
Making Agriculture and Land Use
Climate-friendly and Climate-resilient
1.Enriching soil carbon
2.Creating high-carbon cropping systems
3.Promoting climate-friendly livestock production systems
4.Protecting existing carbon stores in
natural forests and grasslands
5.Restoring vegetation in degraded areas.

Status of Capture Technology
•CO
2capture technologies are in commercial use today,
mainly in the petroleum and petrochemical industries •Capture also applied to several gas-fired and coal-fired boilers, but at scales small compared to a power plant •Net capture efficiencies typically 80-90%•Integration of capture, transport and storage has been demonstrated in several industrial applications, but not yet at an electric power plant
•R&D programs are underway worldwide to develop
improved, lower-cost technologies for CO
2capture;
potential to reduce costs by ~20–30% over near term, and significantly more in longer term
